IMPROVEMENT IN WATCH-CASEBEZELS.

Specification forming part of Letters Patent No. 153,633, dated July 28, 1874; application led November 13, 1673.

To all whom it may concern:

Be it known that I, CHARLES L. THIERY, of Boston, Suffolk county, Massachusetts, have invented certain Improvements in the Manufacture of latch-Cases, i' which the following is a specification This invention is one oi' a series which I have made upon the manufacture oi' Watchcases, and for which several Letters Patent of the United States have been issued to me.

This invention relates to the manufacture of Watch-bezels adapted to hold thick glass crystals, such as recently have come in vogue.

I make the bezel of one homogeneous piece ot metal, preferably using, in the manufacture, the machine described in Letters Patent No. 106,561, ot' August 23, lt'70, now owned by me, and employing` a process of manufacture analogous to that set forth in my Letters Patent No. 96,032, of November 9, 1869.

The above will suiiice to indicate to one skilled in the art the manner in which my improved bezel can be produced. I shall now proceed to indicate, by reference to the accompanying drawing, the features characterizing said bezel.

Figure 1 is a sectional elevation oi" the glass bezel made of one entire homogeneous piece of metal Without solder or joints. Fig. 2 is a longitudinal section of the same.

The bezel is made of sheet metal. It has a horizontal. base, a; an upwardly-extending side, b, inclined and preferably curved, as shown; a ledge, o, slightly beveled, so that its upper edge will overhang a little its lower part; and an internal slanting supportingface, d, which extends down nearly to the plane of base a. On the incline supportingtace d the correspondingly-beveled periphery of the thick glass crystal rests, and is held tightly by the ledge c, the upper edge of which snaps or closes over the top edge of the crystal, when the latter is forced down into the bezel and against the inclined face d.

A bezel is thus produced Well adapted to hold and support the thickest crystal in use, while, in the construction of the bezel itself, there is considerable economy of material, only so much metal being used asis indispensable, the bezel, as seen, being quite tubu-` lar or hollow.

I do not broadly claim making watch-bezels ot' one homogeneous piece of metal; but

Y hat I do claim, and desire to secure by Letters Patent, is-

The watch-case bezel of one homogeneous piece oi" metal, formed as shown and described,A with base-liange a, inclined exterior b, ledge c, and inclined interior supportingi'aec d, for the purposes set forth.
